Final answer:
The question tackles the roles of heavier-gauge and lighter-gauge windings in a solenoid-operated starter, relating to the creation and maintenance of magnetic force to engage the starter mechanism of an automobile.
Step-by-step explanation:
The question involves the understanding of how solenoid-operated starters work in the context of Physics and electrical engineering. Tech A suggests that heavier-gauge winding in the starter's solenoid is responsible for maintaining the magnetic force needed to keep the plunger (or armature) engaged or in position. On the other hand, Tech B believes that the lighter-gauge winding is necessary for creating a magnetic field strong enough to initially draw the plunger into the solenoid when the starter is activated.
Referring to the principles of a solenoid's functionality, the solenoid consists of a coil of wire (solenoid) wrapped around a metallic core, through which an electrical current passes. When this occurs, a strong magnetic field is created inside the solenoid, proportional to the number of turns in the winding and the current passing through it. The magnetic field is uniform and strong within the solenoid, sufficient to move the plunger or engage the starter motor's drive gear with the engine's flywheel, allowing the engine to start.
